TECHNICAL FIELD The present invention relates to the field of communication technology, and more particularly to an information processing method, device and communication equipment.

A preemptive Buffer Status Report (BSR) is a BSR report that is triggered based on the received BSR or data expected to be received. A preemptive BSR can trigger the transmission of a scheduling request (SR), but after triggering the preemptive BSR, an integrated access backhaul (IAB) mobile terminal (Mobile Termination, MT) can It needs to wait for a transmission opportunity, and after sending the SR, the IAB MT also needs to wait for the scheduling of the parent IAB node. However, the data expected to be received may already have changed when attempting to transmit a preemptive BSR after receiving an uplink transmission grant from the parent IAB node. In this case, since the preemptive BSR trigger condition has been removed or changed, sending a preemptive BSR that does not contribute to the scheduling of the parent IAB node will interfere with the uplink scheduling of the parent IAB node.

Embodiments of the present invention provide an information processing method, apparatus and communication equipment to solve the problem that the transmission of preemptive BSR in the prior art may interfere with uplink scheduling.

In order to describe the technical solutions of the embodiments of the present invention more clearly, the following briefly describes the drawings used in the embodiments of the present invention; These are only a few examples, and one of ordinary skill in the art may derive from these drawings other drawings without creative effort.

In order to facilitate understanding of the embodiments of the present invention, first, the following contents will be explained.

Please refer to FIG. 1, which is a structural schematic diagram of an IAB system in an embodiment of the present invention. In an IAB system, an IAB node includes a Distributed Unit (DU) function and a Mobile Termination (MT) function. Through MT, an access point (i.e., IAB node) finds an upstream access point (i.e., parent IAB node), and establishes a wireless connection between the upstream access point's DU and a backhaul link. can be established. Once the IAB node has established a complete backhaul link, it turns on its DU function, which can provide cell services, ie, access services to User Equipment (UE). A self-backhaul loop includes a serving donor IAB node (also called an IAB donor), and there is a wired transmission network directly connected with the donor IAB node.

A structural diagram of the Centralized Unit-Distributed Unit (CU-DU) of the IAB system may be as shown in FIG. In the self-backhaul loop, the DUs of all IAB nodes are connected to the same CU node, which arranges for the DUs according to the F1-AP protocol. The CU deploys the MT according to Radio Resource Control (RRC) protocol. A Donor IAB node does not have an MT function.

The IAB system solves the situation of insufficient wired transmission network deployment when the access points are densely deployed, that is, the access points can use the wireless backhaul when there is no wired transmission network. It was introduced for

In an embodiment of the present invention, BSR types may be divided into at least the following two types. 1) Regular BSR (Regular BSR): The Regular BSR is a logical channel with a higher priority than the current logical channel with data transmission (Logical Channel, LCH) If the LCH changes from no data transmission to data transmission, all If one LCH changes to data transmission when the LCH is no data transmission, when at least one LCH still has data to transmit when the retransmission BSR timer (retxBSR-Timer) times out Either may be triggered. 2) Periodic BSR: The Periodic BSR may be triggered when the Periodic BSR Timer (periodicBSR-Timer) times out.

The LCH belongs to a logical channel group (LCH Group, LCG), the BS (buffer size) of the BSR is reported in LCG units, and up to 8 LCGs can be arranged. A Regular BSR can trigger the transmission of an SR. A retransmission of an SR can be triggered if a grant is not granted after the previous transmission of the SR.

In an embodiment of the invention, the preemptive BSR is a pre-emptive BSR. A preemptive BSR can be triggered based on the received BSR or data expected to be received. Note that the received BSR may indicate the presence of data expected to be received.

In order to reduce the transmission delay of uplink data, the IAB node may trigger a pre-emptive BSR after receiving the BSR (or SR) of the UE or downstream IAB node, or the IAB node may receive A pre-emptive BSR may be triggered if there is expected data. The data expected to be received may be determined by the uplink transmission grant sent to the downstream IAB node or the served UE. After triggering the preemptive BSR, the transmission of the SR can be triggered to request uplink transmission resources, and if the uplink transmission resources are obtained, the IAB node generates a preemptive BSR and transmits it to the parent IAB node. and cancel the preemptive BSR. Here, the preemptive BSR may only be transmitted in the long BSR format and occupies 3-11 bytes depending on the LCG of the data expected to be received.

The time interval from triggering preemptive BSR to transmission mainly depends on the period of SR resources, the scheduling of the parent IAB node, the configuration of physical layer transmission parameters, and so on. The time interval from the triggering of the preemptive BSR to the generation of the Media Access Control (MAC) protocol data unit (PDU) containing the preemptive BSR is several milliseconds to several tens of milliseconds, or even longer. may become

Please refer to FIG. 3, which is a flow chart of an information processing method provided in an embodiment of the present invention, wherein the method includes a relay device (such as an IAB node device or other scene). relay equipment). As shown in FIG. 3, the method includes the following steps.

Step 301: Trigger a preemptive BSR.

In this embodiment, a pre-emptive BSR can be triggered based on the received BSR or data expected to be received.

Step 302: Cancel the preemptive BSR according to a first situation in the process from triggering the preemptive BSR to generating the preemptive BSR.

Optionally, said first situation is
reception status of uplink data, which may be the reception status of data expected to be received upon triggering the preemptive BSR;
and triggering conditions of a target BSR that is at least one of a regular BSR and a periodic BSR.

That is, the relay equipment (e.g., IAB MT) in this embodiment, from triggering a preemptive BSR based on the received BSR or data expected to be received, to receiving an uplink transmission grant (or constructing a MAC PDU) , the uplink data reception status and/or the trigger status of the target BSR (regular BSR and/or periodic BSR) may determine whether to cancel the preemptive BSR. This preemptive BSR cancellation can be understood as a preemptive BSR transmission cancellation or a triggered preemptive BSR cancellation.

According to the information processing method of the embodiment of the present invention, after triggering the preemptive BSR, depending on the situation in the process from triggering the preemptive BSR to generating the preemptive BSR, such as the reception situation of uplink data and/or the triggering situation of the target BSR, can cancel the preemptive BSR. Thus, resources can be saved by avoiding transmission of invalid preemptive BSRs, and interference with uplink scheduling due to invalid preemptive BSRs can be avoided.

In embodiments of the present invention, a scheme for canceling a preemptive BSR after it has been triggered may include any one of the following.

(1) Cancel the preemptive BSR when data expected to be received is received in the process from triggering the preemptive BSR to generating the preemptive BSR.

As a method of canceling the preemptive BSR in (1), specifically, the preemptive BSR is canceled only after all the data expected to be received is received. For example, in the process of constructing a MAC PDU carrying a preemptive BSR, the IAB MT cancels the triggered preemptive BSR if the data expected to be received is 0, i.e. all the data expected to be received has been received. can do. An IAB MT does not cancel a triggered preemptive BSR if it receives only part of the data it expects to receive.

According to the method in this (1), when the IAB MT generates a preemptive BSR and puts it in the MAC PDU, depending on the reception status of uplink data during the period from the trigger of the preemptive BSR to the generation of the preemptive BSR, It can be determined whether all the data corresponding to the BSR from the downstream node or UE, or the data expected to be received as determined by previously issued uplink transmission grants, has been received, The transmission of the preemptive BSR can be canceled when done, ie when the data expected to be received is zero.

For example, as shown in FIG. 4, UE or IAB node 1 triggers transmission of an SR to IAB node 2 based on the BSR, and IAB node 2 grants permission to UE or IAB node 1 before Received a MAC PDU carrying a BSR sent by node 1 and triggered a preemptive BSR. IAB node 2 then triggered sending an SR to IAB node 3 based on the preemptive BSR and received a grant from IAB node 3 . in this case,
When the IAB node 2 receives all data expected to be received in the process from the trigger of the preemptive BSR to the generation of the preemptive BSR (construction of MAC PDU), that is, when all the data expected to be received is received At the same time, the transmission of the preemptive BSR can be canceled, i.e. the constructed MAC PDU sent to the IAB node 3 does not contain the preemptive BSR, or the MAC PDU containing the preemptive BSR is sent to the IAB node 3. do not. In this way, IAB node 2 can avoid sending invalid preemptive BSRs to save resources, and can avoid interference with the scheduling of the parent IAB node (IAB node 3) due to invalid preemptive BSRs. .

(2) in the process from triggering the preemptive BSR to generating the preemptive BSR, if the data corresponding to the LCG with the highest priority among the first data is received, the preemptive BSR is canceled, and the first data is received; is the expected data.

Specifically, the preemptive BSR cancellation method of (2) cancels the preemptive BSR only after all data to be received corresponding to the expected high-priority LCG is received. For example, in the process of constructing a MAC PDU carrying a preemptive BSR, the IAB MT may cancel the triggered preemptive BSR if all the data to be received corresponding to the expected high priority LCG has been received. can. Do not cancel the triggered preemptive BSR if the IAB MT receives part of the data to be received corresponding to a high priority LCG.

According to the method in this (2), the IAB MT receives all the data corresponding to the high-priority LCG among the data expected to be received in the period from the trigger of the preemptive BSR to the generation of the preemptive BSR. , the transmission of the preemptive BSR can be canceled.

For example, as shown in FIG. 5, UE or IAB node 1 triggers sending an SR to IAB node 2 based on the BSR, and IAB node 2 grants permission to UE or IAB node 1 before Received a MAC PDU carrying a BSR sent by node 1 and triggered a preemptive BSR. IAB node 2 then triggered sending an SR to IAB node 3 based on the preemptive BSR and received a grant from IAB node 3 . in this case,
When the IAB node 2 receives all the data to be received corresponding to the high priority LCG among the data expected to be received in the process from triggering the preemptive BSR to generating the preemptive BSR (building the MAC PDU) At the same time, the transmission of the preemptive BSR can be canceled, i.e. the constructed MAC PDU sent to the IAB node 3 does not contain the preemptive BSR, or the MAC PDU containing the preemptive BSR is sent to the IAB node 3. do not. In this way, IAB node 2 can avoid sending invalid preemptive BSRs to save resources, and can avoid interference with the scheduling of the parent IAB node (IAB node 3) due to invalid preemptive BSRs. .

(3) in the process from triggering the preemptive BSR to generating the preemptive BSR, if the target BSR is triggered and the first priority is greater than or equal to the second priority, cancel the preemptive BSR, and the first priority is the priority of the highest priority LCG corresponding to the target BSR, and said second priority is the priority of the highest priority LCG corresponding to the data expected to be received.

Specifically, the preemptive BSR cancellation method of (3) cancels the preemptive BSR according to the trigger status of the regular BSR and/or the periodic BSR. For example, the IAB MT triggers a regular BSR and/or periodic BSR before constructing a MAC PDU carrying a preemptive BSR, and the priority of the highest priority LCG reported by the regular BSR and/or periodic BSR is the preemptive BSR A triggered preemptive BSR can be canceled if it is equal to or greater than the priority of the highest priority LCG reported by .

According to the method in this (3), when the preemptive BSR is generated, the regular BSR and/or periodic BSR have already been triggered, and the highest of the LCGs with data indicated by the regular BSR and/or periodic BSR A preemptive BSR can be canceled if the priority of the priority LCG is greater than or equal to the priority of the highest priority LCG among the LCGs expecting to receive data.

For example, as shown in FIG. 6, UE or IAB node 1 triggers transmission of an SR to IAB node 2 based on the BSR, and IAB node 2 grants permission to UE or IAB node 1 before Received a MAC PDU carrying a BSR sent by node 1 and triggered a preemptive BSR. IAB node 2 then triggered sending an SR to IAB node 3 based on the preemptive BSR and received a grant from IAB node 3 . in this case,
IAB node 2, in the process from triggering the preemptive BSR to generating the preemptive BSR (construction of MAC PDU), the regular BSR and / or periodic BSR has already been triggered, indicated in the regular BSR and / or periodic BSR, the data When the first priority, which is the priority of the highest priority LCG among the LCGs with data, is equal to or higher than the second priority, which is the priority of the highest priority LCG among the LCGs expecting data reception , the transmission of the preemptive BSR can be canceled, i.e. the constructed MAC PDU sent to the IAB node 3 does not contain the preemptive BSR, or the MAC PDU containing the preemptive BSR is not sent to the IAB node 3. . In this way, IAB node 2 can avoid sending invalid preemptive BSRs to save resources, and can avoid interference with the scheduling of the parent IAB node (IAB node 3) due to invalid preemptive BSRs. .

(4) In the process from triggering the preemptive BSR to generating the preemptive BSR, if the target BSR is triggered and the MAC PDU for carrying the preemptive BSR cannot carry the preemptive BSR and the target BSR at the same time, the preemptive BSR is generated. Cancel.

As the method of canceling the preemptive BSR of (4), specifically, whether or not to cancel the preemptive BSR is determined based on the available MAC PDU capacity. For example, if the regular BSR and/or periodic BSR is already triggered before the IAB MT constructs the MAC PDU carrying the preemptive BSR, and the capacity of the MAC PDU is insufficient to carry the regular BSR and/or periodic BSR and the preemptive BSR at the same time. A triggered preemptive BSR can be canceled if there is not enough.

For example, as shown in FIG. 7, UE or IAB node 1 triggers transmission of an SR to IAB node 2 based on the BSR, and IAB node 2 grants permission to UE or IAB node 1 before Received a MAC PDU carrying a BSR sent by node 1 and triggered a preemptive BSR. IAB node 2 then triggered sending an SR to IAB node 3 based on the preemptive BSR and received a grant from IAB node 3 . in this case,
IAB node 2, in the process from triggering the preemptive BSR to constructing the MAC PDU, if the regular BSR and / or periodic BSR has already been triggered, and the MAC PDU carries the regular BSR and / or periodic BSR and the preemptive BSR at the same time. transmission of the preemptive BSR can be canceled, i.e. the constructed MAC PDU sent to the IAB node 3 does not contain the preemptive BSR or the MAC PDU contains the preemptive BSR. to IAB node 3. In this way, IAB node 2 can avoid sending invalid preemptive BSRs to save resources, and can avoid interference with the scheduling of the parent IAB node (IAB node 3) due to invalid preemptive BSRs. .
